I noticed small amount of oil collecting under the groove at the front of the oil pan below the front crankcase cover. How hard is it to replace the oil seals and the oil pan gasket--figured I would do all three. Do yo have to remove the radiator and do you need any special tools. I would appreciate it if one of you experts (that's eliminates me) could give me a general step by step on this and if a neophyte like me can do it. I have removed the radiator before, done the trailing arms, tie rods, shocks, new front springs, etc but not this job. I don't want to screw anything else up. Thank you for all your help in advance.:lookinup: :lookinup:

No real big tricks for this one. The front seal is a press in that fits into the front cover. You need to remove the fan, fan shroud and the front pulley from the crank. The only special tool is a puller/installer for the balancer. IT can be done without pulling the radiator, so that makes it easier too.
If you're going to drop the oil pan and replace the gasket there too, you need to drop the idler arm. That can be done 2 different ways- either take the nut off the steering linkage and split it there or take the 2 bolts off that hold the idler to the frame. All that needs to happen is the steering linkage needs to be dropped down so you can get the oil pan down.
If you decide to pull the oil pan, I'd think about pulling the front cover and replacing the timing chain and gears at the same time. It just might save you from having to do it all over again if the chain/gears fail.
Same for the rear main seal- if the pan is off, it'd be a good time to replace that too. I put together a tips & tricks paper for the rear main seal that's around here someplace.

All what was said above. Minimum you have to loosen the front of the oil pan as the 2 forward bolts that hold the pan also attach to the front cover. If the cover isn't coming out note that it probably is hanging up on the pan. Once out note the part of the cover that is the internal seal that upon re-installation can be SLIGHTLY trimmed to make installation easier. Hard to invision, but once out, not to hard to understand. Also, pay attention to how the balancer looks. They are known to wear a grove where the seal contacts it. This is common enough that there is a repair sleeve available, or the alternative is to replace the balancer. If the balancer is origional, there is a good chance it should be replaced anyway as the rubber mounting ring goes away over time and the outside part of the balancer will shift and cause issues when trying to set timing....or worse, harmonic issues. Just inspect it when you have it out.
